Viral testing remains the backbone of an effective pandemic response until vaccines are widely available. Testing helps us understand the size and nature of localized outbreaks. Paired with contact tracing and supported isolation, robust viral testing gives communities the control they need to safely open, provided they also require best-practice measures such as distancing, mask-wearing and hand washing.

HGHI modeling provides testing target data for states and the nation overall to guide how much testing capacity we need to build and apply to curb the spread of COVID-19.   

This page provides an overview of our testing data work.
